Just in case you haven't been following the intra-Asia chart discussion on the Delta forum, a heads-up: the Northern Asia chart has been amended so that the intra-China mileage requirements for award tickets are based on length of domestic Chinese flight in kilometers. So whatever you thought of the changes, it's even worse. I am curious to know if flights from mainland to "Taiwan, Province of" are counted as intra-China.
